Seymour Krelboin is a hapless sap working in a skid row flower shop. He loves coworker Audrey Fulquard, but is close to losing his job. Luckily, he discovers a new plant, and brings the sickly specimen to work, which impresses both Audrey and his boss, Gravis Mushnick. Mushnick makes Seymour's job contingent on the survival of the plant. While Seymour works on this, he discovers the plant responds to blood. Oh, and it talks! It tells him it needs more blood to thrive, and Seymour sets about the gruesome business of providing it.
Stars: Jonathan Haze, Jackie Joseph, and Mel Welles
